摘要：
G 29-38 is a cool pulsating DA white dwarf with a series of modes from 110 s to over 1000 s found by Kleinman et al.. We present the results of our attempts to find a seismological fit to G 29-38 by looking for a model that identifies most of the observed modes as l = 1 modes. G 29-38, like several other DAV stars, has a discrepancy between the spectroscopically favored mass of about 0.70M. and the parallactic mass of about 0.85M.. Our preliminary model has a mass of 0.75M. and a hydrogen layer mass of 5 x 10(-7)M(star), and it requires that most modes be l = 1.
